JOURNAL-BEARING.

Application filed August 3,

T 0 all whom it may concern:

Be it known that I, ALBERT B. RAY, a citizen of the United States,residing at Shreveport, in the parish of Caddo and State of Louisiana,have invented new and useful Improvements in Journal-Bearings, of whichthe following is a specification:

This invention relates to journal boxes and especially to journal boxesfor the dr1ving shafts of locomotives.

An object of the invention is to provide means for quickly and easilyremoving and replacing a lateral plate to or from the face of alocomotive driver between boxes without removing the driving wheels fromthe frame.

To this end the invention comprehends the novel form of interlockingengagement be tween the driver journal box and the lateral plate, so asto provide a ready and positive engagement, permitting the plate to beconveniently positioned and guarding against its accidentaldisplacement.

The invention further consists of the following novel details ofconstruction combination and arrangement of parts, to be hereinaftermore fully described and illustrated in the accompanying drawings In thedrawings Figure 1 is a front elevation of a driving box with the lateralplate'applied;

Fig. 2 is a fragmentary plan view of a portion of the driving box alsoshowing the lateral plate in position;

Fig. 3 is a sectional view on the line 3-3 of Fig. 1;

Fig. a is a similar view on the line 4:--4: of Fig. 1;

Fig. 5 is a fragmentary perspective view showing the face of the drivingbox;

Fig. 6 is a perspective view looking at the i nner face of the lateralplate;

Fig. 7 is a similar view of one of the keys;

Referring to the drawings'in detail, like characters of reference denotecorrespond ing parts throughout the several views.

As illustrated in the drawings, there are. various ways of carrying theinvention into practice. one of which is shown inFigs. 1 to 7 inclusive.In these figures the numeral 14: represents the face plate of a drivingbox such as is employed with the driving shafts of locomotives. This boxincludes the usual roan brass l5 and cellar 16. Itis custom-Specification of Letters Patent.

ary in bearings of this character to position between the face plate 14:and the adjacent face of the driving wheel, a lateral plate and thepresent invention has to do with this plate and particularly to themeans for securing the said plate to the driving box. For this purposethe face alate 14: of the driving box is vertically grooved as shown at17 and the inner face of the lateral plate 18 is pro vided with lugs 19,the said lugs and grooves 17 being clove-tailed in cross section so asto provlde an interlocking engagement between the plate and the drivingbox. These grooves and lugs extend a relatively short distance downwardfrom the top of the driving box, preferably terminating short of theopening for the driving shaft. Also formed in the face of the plate 14Lare transversely extending grooves 20, these grooves being positionedsubstantially diametrically with respect to the driving shaft.

The plate 18 is provided upon each side thereof with side wings orflanges 21. which are adapted to contact with the sides of the drivingbox. Openings 22 are formed in the plates 21, these openings registeringwith and being of substantially the same size and shape as the grooves20. Transversely slidable keys 23, also of the same size and shape asthe grooves 20. pass through the openings 22 and enter the said groovesto provide an interlocking engagement between the lateral plate and thedriving box. I

In order to prevent the accidental removal of the keys 23, outwardlyextending lugs 24 are positioned at each end of the openings 22, theselugs being provided'with allned openings 25,*which are adapted toregister with an opening 26 provided in each of the keys 23. A bolt orpin 27passes through the openings in the ears 24 of the key 23, to holdthe latter in position. If desired a cotter pin 28 may extend throughthe bolt 27 beneath the nut 29 to prevent accidental removal of thisnut. As an additional securing means, machine bolts 30 are passedthrough the side flanges 21 and engage openings in the sides of the faceplate 14, a plate or malleable metal 31 having one end bent to engageone of the side edges of the head of the bolt 30 to provide a lockagainst the accidental removal of this bolt.

It is believed that when the foregoing description is read in connectionwith the accompanying drawings, that the construction, operation andadvantages of the invention Will be apparent. Various changes may bemade in the form and proportion thereof and the right is reserved tomake such changes as properly fall Within the scope of the appendedclaims.

Having described the invention, What is claimed is 1. The combinationwith a driving box,

o a lateral plate, side flanges carried by said plate for contact witheach side of the driving box, vertically and transversely 'dis posedgrooves formed in the face of the driving box, dove-tailed lags carriedby the lateral plate for engagement with the vertically disposedgrooves, transversely extending keys passing through openings in theside flanges of the lateral plate and engageabla with the horizontallydisposed grooves and means for preventing the accidental removal of thekeys.

2. The combination with a driving box having vertically and transverselyextending grooves in the face thereof, of a lateral plate, side flangescarried by said plate for contact with each side of the driving boxes,means carried by the lateral plate for en- ;elnent with the verticallyextending grooves means extendinginwardly from the side flanges forengagement with the horizontally extending grooves and means forpreventing accidental disengagement of the engagingmeans. e
